How is coloured glass used to preserve food and drink?
1) “Fluorescent lighting in retail dairy display cases induces vitamin A degradation and ‘light-oxidized’ flavor defects in milk products packaged in light-transmissible … containers.” “Although it is not possible to estimate the cost of the thousands of illnesses and even deaths caused by food that has become unsafe for consumption, there is a great deal of research available on the financial cost to the retailer due to the loss of proper shelf life after perishables are exposed to light. There is no doubt that this is the most important reason for retailers to consider the relationship between radiation from light sources and food shelf life. Visible and invisible radiation from light sources has a harmful effect on the shelf life of food. It is not only the UV and infrared cycles of the spectrum that damage food. There is considerable literature that connects the photochemical oxidation of most food groups to the wavelengths of visible radiation that these foods are exposed to.” S
